NASA's TRMM satellite sees some towering thunderstorms around Faxai's center
Towering thunderstorms and heavy rainfall were occurring around the center of Tropical Storm Faxai in the Southwestern Pacific Ocean, and were seen by the TRMM satellite.

The surface of the sea is a sink for nitrogen oxides at night
The surface of the sea takes up nitrogen oxides that build up in polluted air at night, new measurements on the coast of southern California have shown. The ocean removes about 15 percent of these chemicals overnight along the coast, a team of atmospheric chemists reports in the early online edition of the Proceedings of the National Academy of Sciences the week of March 3.

Global warming felt to deepest reaches of ocean
A new study led by researchers from McGill University suggests that the the 1970s polynya in the Antarctic sea ice pack of the Weddell Sea may have been the last gasp of what was previously a more common feature of the Southern Ocean, and which is now suppressed due to the effects of climate change on ocean salinity.

What sculpted Africa's margin?
Break-up of the supercontinent Gondwana about 130 Million years ago could have lead to a completely different shape of the African and South American continent with an ocean south of today's Sahara desert.

Competition breeds new fish species, study finds
Size differences among fish and competition for breeding space lead to the formation of new species, according to a new study by researchers from the University of Bristol published today in Nature Communications.

Study projects big thaw for Antarctic sea ice
A new modeling study suggests that a recent observed increase in summer sea-ice cover in Antarctica's Ross Sea is likely short-lived, with the area projected to lose more than half its summer sea ice by 2050 and more than three quarters by 2100. These changes will significantly impact marine life in what is one of the world's most productive and unspoiled marine ecosystems.

New invasive species breakthrough sparks interest around the world
A research breakthrough at Queen's University Belfast has sparked interest among aquatic biologists, zoologists and ecologists around the world. The joint research between Queen's and several South African institutions centered on the behavior of some of the 'world's worst' invasive species, including the large-mouth bass, an invasive fish which typically devastates invertebrate and other fish communities wherever it is introduced.

Altruistic suicide in organisms helps relatives
The question of why an individual would actively kill itself has been an evolutionary mystery. Death could hardly provide a fitness advantage to the dying individual. However, a new study has found that in single-celled algae, suicide benefits the organism's relatives.

Ambitious new pollution targets needed to protect Lake Erie from massive 'dead zone'
Reducing the size of the Lake Erie 'dead zone' to acceptable levels will require cutting nutrient pollution nearly in half in coming decades, at a time when climate change is expected to make such reductions more difficult.

Spotted seal study reveals sensitive hearing in air and water
Two spotted seals orphaned as pups in the Arctic are now thriving at UC Santa Cruz's Long Marine Laboratory, giving scientists a rare opportunity to learn about how these seals perceive their environment. In a comprehensive study of the hearing abilities of spotted seals, UCSC researchers found that the seals have remarkably sensitive hearing in both air and water.

Where have all the codfish gone?
The mega-decline in cod and other fisheries across the North Atlantic Ocean threatens the livelihood of fishermen and communities in New England and Atlantic Canada. One suspect in the disappearance of cod and other groundfish is the food source for their young: a planktonic copepod crustacean. The first transcriptome for the key North Atlantic copepod Calanus finmarchicus has been published; scientists will use it to decode the genetic instructions that are resulting in population changes.

Ecotoxicity: All clear for silver nanoparticles?
It has long been known that, in the form of free ions, silver particles can be highly toxic to aquatic organisms. Yet to this day, there is a lack of detailed knowledge about the doses required to trigger a response and how the organisms deal with this kind of stress. To learn more about the cellular processes that occur in the cells, scientists from the Aquatic Research Institute, Eawag, subjected algae to a range of silver concentrations.

Smithsonian scientists solve 'sudden death at sea' mystery
Modern whale strandings can be investigated and their causes identified. Events that happened millions of years ago, however, are far harder to analyze -- frequently leaving their cause a mystery. Smithsonian and Chilean scientists examined a large fossil site in the Atacama Desert of Northern Chile -- the first definitive example of repeated mass strandings of marine mammals in the fossil record. It reflected four distinct strandings over time, indicating a repeated and similar cause: toxic algae.

It's all water over the dam -- but how and when it falls has huge impact on salmon
By adjusting water discharges in ways designed to boost salmon productivity, officials at a dam in central Washington were able to more than triple the numbers of juvenile salmon downstream of the dam over a 30-year period. The research shows that keeping eggs and young salmon under water at especially vulnerable times boosts survival.

New digital atlas details Alaska sea ice history since 1860

This data set provides researchers with a reliable tool to evaluate climate change impacts.

EARTH Magazine: Tsunamis from the sky
Only recently have scientists unraveled how a storm can create and propagate these far-traveling waves -- called meteorological tsunamis or meteotsunamis. The waves, which arise out of a complex interplay of storm speed, wave dynamics and ocean-bottom bathymetry, may be less common than seismic tsunamis, but they can still be destructive and deadly.
